Japanese architect Sou Fujimoto has been named as the designer of this year’s Serpentine Gallery Pavilion – and at 41 years old will be the youngest designer to have completed the renowned temporary commission.

The “transparent and lightweight” cloud-like structure, made from a lattice of steel poles, will take up 350sqm of lawn outside the London gallery. The pavilion will include a cafe and multi-purpose social space.

“The delicate quality of the structure, enhanced by its semi-transparency, will create a geometric, cloud-like form, as if it were mist rising from the undulations of the park,” said Fujimoto in a statement. “From certain vantage points, the pavilion will appear to merge with the classical structure of the Serpentine Gallery, with visitors suspended in space.”

Fujimoto is the third Japanese architect chosen to design the pavilion, with Toyo Ito (2002) and SANAA (2009) having previously taken part. Last year’s pavilion was designed by Herzog & de Meuron with Ai Weiwei, and saw a floating circular platform filled with shallow water resting on 12 columns – each representing a pavilion constructed over the project’s twelve years.
